Some upper-scale restaurants charge you a "no-show" fee, using the credit card used for the reservation. Maybe airlines could do this? (Of course, the difference is that restaurants don't receive the actual payment for services with no-shows.)

Why would that make sense for airlines? Missing a flight and then paying extra sounds awful, especially since the justification is "we could have also sold your seat to someone else."
